The oval lenses in these cool shades for men by X-Loop fit nicely with the overall curved and sweeping look of the sunglasses. The frame is made of plastic, designed to be lightweight, but also strong and rigid for daily wear. The arms are straight with a slight inward curve that adds grip, and they feature the X-Loop logo on the side in a muted carved in letter look. The lenses have a finish that blocks out ultraviolet and keeps your eyes safe while playing sports.
